This is very interesting issue. Please read without any assumption.
I have 2 vCenter. vCenter 5.5 and vCenter 6.5. I have DatasTore 001 mapped to vCenter 5.5.
we have presented the same LUN to vCenter 6.5 as well.
So I am removing VM from 5.5 environment and registering again to 6.5 by registering VMS.
So far I have migrated more than 20 VMs , no isssues.
The issue is that I have one VM in DataStore 002 presented to both 5.5 and 6.5. But I can not see the VM folder when I am looking from 6.5 as if they are different DataStore.
As test, I create an TEST folder from 5.5 in the same DataStore and I am able to see it on the same DataStore from 6.5
Note : ALL LUNS are in SAN and yes ALL DataStores presented all The hosts in both 5.5 and 6.5 hosts
any idea ! and please I am not looking any other way to migrate. Just trying to understand why I am not seeing same files on the same datastore
